This article presents a review of the literature on object permanence with an emphasis on research on children with severe disabilities. Object permanence is the realisation that objects continue to exist in time and place even when they are no longer visible. This understanding is achieved across Stages IV-VI of Piaget's Sensorimotor Period.…

In this paper we critically review the literature on the use of event related potentials (ERPs) to elucidate the neural sources of the core deficits in autism. We review auditory and visual ERP studies, and then review the use of ERPs in the investigation of executive function. We conclude that, in autism, impairments likely exist in both low and…

The goal of this review is to evaluate the literature on binocular coordination during reading and non-reading tasks in adult, child, and dyslexic populations. The review begins with a description of the basic characteristics of eye movements during reading. Then, reading and non-reading studies investigating binocular coordination are evaluated.…

This literature review focuses on the confirmed, suspected, and speculative effects of violent and non-violent video game exposure on negative and positive outcomes. Negative outcomes include aggressive feelings, aggressive thoughts, aggressive behavior, physiological arousal, and desensitization, whereas positive outcomes include various types of…

The ubiquitous left-hemisphere advantage in visual word processing can be accounted for in different ways. Competing theories have been tested recently using cAsE-aLtErNaTiNg words to investigate boundary conditions for the typical effect. We briefly summarize this research and examine the disagreements and commonalities across the theoretical…

Research is reviewed for evidence that female responses to objects, images, and themselves constitute a different perspective or reality from those of males, and whether a different set of constraints exists in the relations between the male artist and his creation and between the female artist and hers.

It is widely assumed that high-level visual processes subserve the attentional blink (AB). Recent evidence from studies of visual masking during the AB that were designed to directly test the contributions of high-level masking effects, however, have failed to provide empirical support for this position.The implication is that low-level visual…

It is argued that a reflectance channel that requires priority information is shown to be less plausible for the human visual system than J. L. Dannemiller (1989) argued. In the response, Dannemiller replies that lightness is not an illuminant invariant surface descriptor when daylight illuminant substitutions are considered. (SLD)

F. Attneave (1954) famously suggested that information along visual contours is concentrated in regions of high magnitude of curvature, rather than being distributed uniformly along the contour. Here the authors give a formal derivation of this claim, yielding an exact expression for information, in C. Shannon's (1948) sense, as a function of…

Research on the effects of visual perception and orientation difficulties on academic, communication, and social development of deaf children is reviewed. The need for incorporating methods for remediating learning disabilities into preservice training for teachers of the deaf is emphasized. (CL)

Argues for the analyzing, studying, and describing of text pages as configurations of columns and lines and as constallations of alphabets. (FL)

Art teachers should be familiar with psychologist's research on human vision and perception. Research by Julian Hochberg, James Gibson, and Gestaltists is summarized. (SR)

Argues that "persistence of vision" myth (the succession of still images perceived as continuous motion) has a place in the history of film scholarship but can no longer be given currency in film theory. Suggests replacement of the concept of the passive viewer implied by the myth by an enlightened understanding of how viewers actually…

A review of research examines the relationship between visual perceptual skills and reading achievement using meta-analysis to integrate statistically the results from 161 studies. It was concluded that visual perceptual skills should be included in the complex of factors predictive of reading achievement. (Author)

This brief overview on dyslexia notes the problems of defining this syndrome, presents a profile of a "typical" dyslexic child, and describes the three sub-types of dyslexia which have been identified. (SJL)
